Why does the frequency of a wave decrease as the wavelength increases?

1 answer:

6 0

Because the product of (wavelength) times (frequency) is always the same number ... the wave speed. Since their product can't change, then obviously if one of them changes, the other one must change in the opposite direction.

Answer:

A. The core makes up the majority of Earth's volume.

A less massive moving object has an elastic collision with a more massive object that is not moving. Compare the initial velocit

stepladder [879]

Assume that the small-massed particle is $m$ and the heavier mass particle is $M$ .

Now, by momentum conservation and energy conservation:

$mv = mv_{m} + Mv_{M}$

$mv^{2} = mv^{2}_{m} + Mv^{2}_{M}$

Now, there are 2 solutions but, one of them is useless to this question's main point so I excluded that point. Ask me in the comments if you want the excluded solution too.

$v_{m} = v\frac{m - M}{m + M}\\\\\\v_{M} = v\frac{m + M}{m + M}\\$
